INTERNALLY COOLED TURBINE PLATFORM

摘要

A turbine flowpath component (100) for a gas turbine engine (20) includes a platform (102) defining at least one internal cooling cavity (140) and a turbine flowpath component cover (120) disposed radially outward of the platform (102). The turbine flowpath component cover (120) defines a radially outward edge of the at least one internal cooling cavity (140) and a transition region (124) in which a radial depth of the at least one internal cooling cavity (140) varies from a first depth to a second depth.
